The principle of first-come-first-served is simple, and
it’s fair
.
Why is first come first serve not efficient?
Disadvantages of FCFS
The Average Waiting Time is high. Short processes that are at the back of the queue have to wait for the long process at the front to finish. Not an ideal technique for time-sharing systems. Because of its simplicity,
FCFS is not very efficient
.
Will be first come first served?
You say ‘first come first served’ to indicate that
a group of people or things will be dealt with or given something in the order in which they arrive
. There will be five buses, first come first served.
What are the advantages of first come first serve?
- It is the simplest and easy to implement algorithm programmatically. The FCFS algorithm is implemented using a FIFO Queue in the data structure. …
- It works well with the processes that have long burst time.
What is the problem with first come first serve?
Disadvantages- It does not consider the priority or burst time of the processes. It
suffers from convoy effect
.
What is the average turn around time using first come first serve?
For FCFS, the average waiting time is (0 + 10 + 39 + 42 + 49) / 5 =
28 ms
. For nonpreemptive SJF scheduling, the average waiting time is (10 + 32 + 0 + 3 + 20) / 5 = 13 ms.
What is the meaning of first come first serve?
—used to say that
the people who arrive earliest get served or treated before the people who arrive later The campsites are first

What is a disadvantage of first-come first served Mcq?
Explanation : Note that the FCFS scheduling algorithm is nonpreemptive ,the major Disadvantages of FCFS policy is
the average waiting time under the FCFS policy is often quite long
.
What burst time?
Burst Time refers
to the time required in milli seconds by a process for its execution
. The Burst Time takes into consideration the CPU time of a process. The I/O time is not taken into consideration. It is called as the execution time or running time of the process.
What are the advantages and disadvantages of first come first serve?
- Advantages – It is simple and easy to understand.
- Disadvantages – The process with less execution time suffer i.e. waiting time is often quite long. Favors CPU Bound process then I/O bound process.
What is the major disadvantage of priority scheduling?
Disadvantages of priority scheduling
If the
system eventually crashes, all low priority processes get lost
. … This scheduling algorithm may leave some low priority processes waiting indefinitely. A process will be blocked when it is ready to run but has to wait for the CPU because some other process is running currently.
What are the disadvantages of CPU?
In addition to the proper heat sink, you may need additional cooling fans inside the computer case, or even a liquid cooling system.
Failing to dissipate the heat that a processor
emits can cause irreparable damage to the processor itself and to other components.
